Why Do I Need A Network Time Server? Computers have notoriously inaccurate clocks. They often use cheap, inferior, crystals and clock components. After a relatively short period of time, the clocks of two or more computers will significantly differ. For transaction processing, trading, data logging, and many other applications a consistent network time is imperative […]

Installing a T-Series GPS\GNSS NTP Server
Locating the Appliance TimeTools T-Series NTP server appliances should only be installed indoors. Locate the device in a rack, on a shelf, or in a cupboard. It should not be supported by the attached cables. Antenna Positioning Ideally, a GPS\GNSS antenna should be positioned in a location where the top of the antenna has a […]
NTP Hardware Reference Clocks: GPS, Multi-GNSS or Radio ?
There are a number of sources of accurate time available to timing applications. They divide into satellite navigation systems and national time and frequency radio broadcasts. TimeTools T-Series NTP servers use either GPS or Multi-GNSS timing references. Below is a list the associated advantages and disadvantages of each. GPS (Global Positioning System) GPS (Global Positioning […]
Secure NTP Server
The Network Time Protocol (NTP) is an Internet protocol built to distribute precise time around a computer network. NTP makes use of UDP over TCP/IP to synchronize network time clients to a precise time reference. This informative article talks about the security and safety elements of the NTP protocol and particularly making use of MD5 […]
T100: Cheap, Inexpensive Compact NTP Server
TimeTools T100 NTP server is a low cost time reference for synchronizing small and medium sized networks. It provides a highly cost effective solution for solving computer timing issues and time critical applications. The T100 receives very accurate time stamps from the Global Positioning System (GPS) which it uses to precisely synchronize its own internal […]
What is a Time Server ?
It is generally recognized that a time server is an appliance used to synchronize time on a PC or computer network. The device will generally obtain accurate time from an external reference and provide a precise time resource for computers. Synchronization of computers and computer networks can be a critical concern for many organisations. Where […]
Leap Seconds and the Network Time Protocol
The international standard of time is Coordinated Universal Time (UTC), which is used in countries around the world almost exclusively as the basis of civil time. UTC is derived from atomic clocks located in the National Physics Laboratories of various countries and is based on the international definition of the second. However, the Earth takes […]
